TUBULAR-TANK INSPECTOR AND GAGE.

Specification of Letters Patent.

Patented April 2, 190'?.

Appiication iiled March 12,1906. Serial No: 305,680.

' Be it known that I, W rLLrAM GREGsoN, a citizen of the United States,residing at' Beaumont, in the county of Je'erson and State of Texas,have invented certain vnew and useful Y 'plm rovements in Tubular-TankInspectors an Gages, of which the following is a specification.

The-present invention relates to improvements in gages, and relatesparticularly to foil-gages and inspectors.

The object of the invention is the provision of a gage for terminatingthe depth of iiuids contained in a tank or other receptacle, and whenusd\for the purpose of measuring crude oil in vessels it serves toascertain the quantity of oil and water in the tank and also thequantity of sediment which is usually found 1floating between the crudeoil and water contained in the tank or reservoir.'

The invention consists of a gage-tube suit# ably secured to a pole andprovided with stoppers or valves at the top and bottoni for preventingthe escape of the fluids contained in :the tube after the gage has beeninserted in- -and withdrawn from a tank, together with means foractuating said4 valves by pressure upon the.pole or by means, ofconnections controllable from the top of the pole.

Further objects and advantages of the invention will be set forth in thedetailed description which now follows.

In' the accompanying drawings, Figure 1 is a front elevai ion of a gage'constructed in accordance with the invention. Fig. 2- is a rearelevation of said gage with the gage-pole removed. Fig. 3 is a sideelevation illustrating the gage attached to the gage-pole, andA Fig. 4is a plan view of the device.

Like numerals designate corresponding parts in all of the figures of thedrawings.

Referring to the drawings, the numeral 5 designates a gage-pole whichmay be of any desired length and which has secured toits lower end atubular casing 6,which forms the body of the gage. 'The tubular casing 6has secured thereto rearwardly-extending clam ing) members 7, which aresecu-red to the po e 5 l y 'screws 8. A glass tube 9 is inserted in thetubular casing 6, which is open at its front portion to render visiblethe contents of said tube. tubular Vcasing 6 and to the clamping members7 and receive the slidably-'disposed valve-rods 11. These valve-rodscarry inwardly-eXtending disks 12, upon the inner Guide-lugs 10 aresecured to the faces of which are mounted pads 13, which are preferablyformed of'leather. These pads constitute valves and serve to close boththe upper and lower ends of the glass tube 9. :x

Pivoted upon the rear face of the tubular casing 6, as at 14, is an arm15, one end of which is connepted, as at 16, to a link 17. The op ositeend of said link is 'connected to one of t e valve-rods 11, as at 18. Alink 19 isconnected at 20 to the other valvefrod 11 'and at 21 to thearm `15. A raise-lug 22 coacts with 4an inclined lug 23, carried by sring-detent 24, to hold the Vvalve-rods at t eir ,limit of movement.Plates 25, having suitablenumbersthereon, are arranged adf jaeentthetube 9 and serve as a gage to indicate the height of the various liquidscon- 1 tained in said tube. A cord or other flexible connection 26 issecured, as at 27, to the free end 4of the lever 15 and passes throughan eyelet 28' to the upper end of the pole. v

The operation of the device is as follows: Assuming the device to be inthe position illustrated in Fig. ,1, With the top and bottom orifices ofthe glass tube open, the ga e is inserted in the tank the contents ofwhich it is desired to measure. As the ole, with the glass tube, passesthrough the different strata of ingredients in the tank a quantity ofoil is first encountered and taken into the lass, then a quantity of thesediment which oats between theoil and water, and finally a uantity ofwater passes into 4the tube. l' henthe lower disk 12strikes the bottomof the tank, the upper andlower valves may be; When it,

closed by pressure upon the pole.

is desired to thus close the valves, sufficient' v pressure 'is appliedto the pole to overcome the-spring-detent-24. The glass tube then isforced down'upon the lower valve-pad ,13. This movement of the tubewithrelation to the lower valve-rod 11 rocks arm 15 upon its pivotv andclosesl the other valve simultane-v ously with the closure of the lowervalve. it is not desired to lower the gage entirely to the bottom of thetank, but it is desired to close the valves when the gage is but partthe Way down-in said tank, the'arm 15 may be rocked upon its pivotalpoint by tilting upon. the cord 26, winch movement of the arm 15 roowill, it is apparent, close the upper and lower valves simu taneously'.

From the foregoing description will be 'seen' that simple and efficientmeans are herein provided for accurately determining Iic the condition0i" the' contents of an oil-tank at any point between the surface of theliquid contained in said tank end the bottom of the tank.

While the elements herein shown sind den scribed are welladapted toserve the purpose for which they are intended, if is to be understoodthat my invention is not limited to the precise construction set forth,vbuit includes within its purview such changes as may be made within thescope of the appended claims.

Having described my invention, what I claim is- 1. In a device of thecharacter described,

the combination with a pole, of an openended tube carried b v said pole7a valve lo'- cated at each end of said tube, means for closi mense ingboth of said valves When pressure is ap.-

plled to Ehe pole, end means for actuating im said valves from the upperend .of th pole.

2. In as'device of the character described the combination with a pole,of an open-` from the upper end of the pole,. and a springdetent forholding seid valves at their limit'y ,of

movement. v In testlmony whereof- I affix my signapure 1n presence oftwo Witnesses.
